Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed May 2'7. 1907. Serial No. 376,011.

T 0 all whom it may concern:

Be it known that we, ELMER E. STOCKTON and ARTHUR H. PORTER, citizens of the United States, residing at Bristol, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Alarn1-Olocks and we do hereby declare the following, when taken in connec tion with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1 a plan view of a clock constructed in accordance with our invention. Fig. 2 a view thereof in rear elevation. Fig. 3 a view thereof in vertical section with the movement plates and pillars in side elevation. Fig. 4 a detached view of the bell and dustguard, the former being shown in plan and the latter being shown in horizontal section on the line o l) of Fig. 2.

Our invention relates to an improvement in nickel alarm clocks, so called on account of having nickeled sheet-metal cases. In recent years these clocks have been provided, to a large extent, with concentrically arranged bells located upon the outside at the back. Such clocks are objectionable in so far as the bell is exposed and as they call for special packing boxes entailing extra expense.

The object of our present invention is to obviate these objections by locating a concentrically arranged bell within the clock .in stead of in an exposed position at the back thereof.

In carrying out our invention as herein shown, we employ a flanged sheet metal bell 2 arranged concentrically within the rear end of a circular sheet-metal case-body 3 and supported, as shown, by two studs 4 having their rear or outer ends shouldered to form bearings for the bell, and threaded for the reception of nuts 5 by means of which the bell is secured in place. The said studs 4 are mounted in a disk-shaped dust-guard 6 located within the rear portion of the case 3 and attached by nuts 7 to the projecting rear ends of the pillars 8 of the clock-movement which is sufficiently indicated for the purposes of the present description by means of the said pillars 8 and the rear movementplate 9 and the front movement-plate 10 forming as it were the movementframe. The said front movementplate 10 is provided with strap-like brackets 11 by means of which the movement is centrally sup ported within the case 3. The rear portion of the movement is also supported by the disk 6 in case the disk is made, as shown, to fit snugly within the case which is desirable, as when so made it best performs its function as a dust guard. The dial 12 is secured to the brackets 11 and supports the mat 13 which in turn supports the glass or crystal 14 which is held in place by a bead or flange 15 turned inward from the front edge of the case 3. In order to prevent the sound of the bell from being muffled, the case 3 is by preference provided with a band of sound-holes 16 located between the dust-guard and the rear edge of the case. The back 17 of the case is fitted in place in the usual way and shuts in the bell 2.

To are aware that it is old to place a wire gong between a clock-movement and the back of a circular case for the movement. 7e are also aware that sound holes have been employed to let out the sound of an inclosed bell. I/Ve do not therefore claim either of these two ideas broadly.

1. In an alarm clock, the combination with a circular case-body the rear portion of which is pierced to form sound holes, of a case-back adapted to be inserted into the open rear end of the said case-body, a movement-frame located within the said casebody, a dust-guard located between the said movement-frame and the said sound holes, and a flanged sheet-metal bell arranged coneentrically within the rear portion of the casebody and located between the said dustguard and case-back, whereby the bell is located inside instead of outside of the casebody and so protected thereby.

2. In an alarm clock, the combination with a circular sheet-metal case-body the rear portion ofwhich is pierced to form sound-holes, of a case-back adaptedto be inserted into the open rear end of the said casebody, a movement-frame located within the said case-body, a dust-guard carried by the said movement-frame and located between the same and the said sound-holes, and a flanged sheet-metal bell carried by the said specification in the presence of two subscribguard, arranged concentrically within the ing witnesses.-

rear portion of the case-body and located be- ELMER E. STOCKTON.

tween the said guard and caseback whereby ARTHUR H. PORTER. 5 the bell is located inside instead of outside of Witnesses:

the case-body and so protected thereby. S. TN. HOWE,

In testimony whereof, we have signed this O. E. INGRAHAM.
